Applieation filed luly 8,1919. Serial No. 309,281.

To all whom it may concern: I

Be it known that I, ERICK BERNHARD PETERSON, a subject of Sweden, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Ball Safety- Catches for Brooches and Articles of a Similar Nature, of which the following is a specification.

My invention has reference to an improve ment in articles of jewelry and more particularly to an improvement in safety catches for brooches and the like.

The object of my invention is to improve the construction of safety catches for brooches, pins, and the like, whereby the construction of the catch is in the nature of a ball and socket joint, the construction simplified and strengthened, liability of solder entering the catch, in soldering the catch to a brooch practically eliminated, and the appearance of the catch greatly improved.

My invention consists in the peculiar and novel construction of a ball safety catch for brooches and similar articles of jewelry, said ball safety catch having details of construction, as will be more fully set forth hereinafter and claimed.

Figure 1 is an end view of a brooch provided with my improved ball safety catch, showing the catch in the open position in full lines and in the closed position in broken lines.

Fig. 2 is a longitudinal sectional View taken on line 2. 2 of Fig. 1 with the catch closed.

Fig. 3 is a top view of the catch in the open position.

Fig. 4: is a transverse sectional view taken on line +t. 1 of Fig. l with the catch open.

Fig. 5 is an inner face view of the keeper blank or partly formed up keeper.

Fig. 6 is a side view of the ball locking member, and

Fig. 7 is an edge view of the ball locking member.

All of the figures in the drawing are greatly enlarged to more clearly show my invention.

In the drawing 1 indicates the body of a brooch or similar article of jewelry, 2 a pintongue and 3 my improved ball safety catch tend from the center outward, and a closed cupped base 9 which raises the body 0 a predetermined distance above the back of the brooch and in the bottom of which is a groove 10 corresponding to the slots 8. Sand which forms practically a continuation of the slots 8. 8 in the keeper.

The locking member 5 is in the form of a solid spherical body 11 having a pin-tongue opening 12 which extends radially from the center outward, and a central annular rib 13 which merges outward into a short op erating member 14-. The spherical body 11 has a movable fit in the hollow globular keeper 4:, it is held in place and guided by the rib 13 in the slots 8. 8 and the groove 10 in the bottom of the keeper, and the operating member 1% extending out through a slot 8 in the keeper. The locking member is secured in the keeper by placing the locking member on the blank or partly formed. keeper and then, by the use of suitable dies, forming the upper portion of the hollow globular body of the keeper around the solid spherical body of the locking member 5.

When in use the pin-tongue is locked in the catch by depressing the pin-tongue into the pin-tongue openings 7. 7 in the keeper and pin-tongue opening 12 in the locking member. The locking member is now given one-half of a revolution in the keeper, by the operating member 14, as shown in broken lines in Fig. 1.

By the use of my improved construction, safety catches, which are necessarily small and heretofore weak in construction, are given the strongest possible construction, as the upper portions of the hollow globular keeper, when formed over the spherical body of the locking member, forms curved rigid arms over the locking member, which positively secures the locking member in the keeper.

It is evident that my improved ball safety catch could be varied in details of construction within the scope of the appended claim.

Having thus described my invention I claim as new A ball safety catch for brooches and the like comprising a hollow globular keeper having oppositely disposed radial pintongue openings, oppositely disposed radial slots and a raised closed base in the bottom of which is a groove forming practically a continuation of the radial slots, a solid spherical locking member in the hollow globular keeper and having a radial pintongue opening, coinciding with the radial pin-tongue opening in the keeper when the catch is open, and an annular rib in and guided by the slots and groove in the keeper, the rib merging into an operating member which extends out through a slot in the keeper, and means for securing the locking member in the keeper, as shown and described.

In testimony whereof, I have signed my name to this specification.

ERICK BERNHARD PETERSON.
